Chapter 56 : Dermatologic Drugs Questions
Question 1 of 5
A child has been diagnosed with impetigo, a skin infection. The nurse anticipates that which drug will be used to treat this condition?
Correct Answer: D
Rationale: Mupirocin is used on the skin for treatment of staphylococcal and streptococcal impetigo. Spinosad is used for pediculosis; nystatin is an antifungal drug; and acyclovir is an antiviral drug.
Question 2 of 5
A 55-year-old obese patient was diagnosed with candidiasis in the skin folds under her breasts. When the nurse sees her at a follow-up visit 2 months later, she complains that it has returned. She said she applied the medicine for 1 week and stopped because the itching stopped and the cream was messy. Which statement is true regarding fungal infections of the skin?
Correct Answer: A
Rationale:
Topical fungal infections are difficult to treat and may require prolonged therapy of several weeks to as long as 1 year. Occlusive dressings should not be applied unless recommended by the medication's manufacturer.
Question 3 of 5
A female patient will be starting therapy with oral isotretinoin as part of treatment for severe acne, and the nurse is providing teaching. Which teaching point will the nurse include in her teaching plan about isotretinoin?
Correct Answer: A
Rationale: It is now required that at least two contraceptive methods be used by sexually active women during and for 1 month after completion of therapy with isotretinoin.
Question 4 of 5
A patient is admitted to the hospital for possible septicemia. He has a large pressure ulcer on his heel that is open and includes necrotic tissue. However, his prothrombin time/international normalized ratio (PT/INR) values are too high to permit surgical debridement at this time. The nurse expects that which wound-care product will be used to treat the wound?
Correct Answer: D
Rationale: Because this patient has an elevated PT/INR, he cannot receive surgical debridement because of concerns about excessive bleeding. Collagenase is useful for patients taking anticoagulants and for those in whom surgery is contraindicated; it selectively removes necrotic tissue but does not harm normal tissue.
Question 5 of 5
The nurse is reviewing laboratory results for a patient and notes that the patient has positive results for nasal colonization by methicillin-resistant Staphylococcus aureus (MRSA). The nurse anticipates an order for which medication?
Correct Answer: B
Rationale: Mupirocin (Bactroban) is used on the skin for treatment of staphylococcal and streptococcal impetigo. It is used topically and intranasally to treat nasal colonization by MRSA; however, MRSA is becoming increasingly resistant to the drug.
